Custom error reporting script

[Join us @ facebook]

Is there any custom script that can be used for logging the php errors?

I have setup my server so it wont show any error, but I would like to have the abillity to know when an error occures

I have not seen a script like this, but I will let you know if I see one.

Ok. I figured it out. Here is the solution :

Code:

<?php
 function handler($errno, $errstr, $errfile, $errline)
 {
        $fp = fopen($_SERVER["DOCUMENT_ROOT"] . "/error.log", "w");
        fwrite( $fp, date("Y-m-d") . " Error $errno : $errstr in lile $errline of file $errfile\n" );
        fclose($fp);
 }
 set_error_handler("handler");
?>

Put this on every page of your site, and you'll have a simple error logging script.

Ah, very useful when you are developing scripts. Thanks

I generally dont use this sort of method but I will try it out.

Great stuff you shared there Nikolas!

By applying this script to the whole site you are sure that your site runs ok without problems.

Great script! and really simple.

I allways wanted something to tell me if there are problems in the server.

I've puted a line to email me the error, so I can sleep at night now...

Thanks for the information Nikolas

I made a small fault in the code I submitted. The right code is :

Code:

<?php
function handler($errno, $errstr, $errfile, $errline)
{
        $fp = fopen($_SERVER["DOCUMENT_ROOT"] . "/error.log", "a");
        fwrite( $fp, date("Y-m-d") . " Error $errno : $errstr in lile $errline of file $errfile\n" );
        fclose($fp);
}
set_error_handler("handler");
?>

Thats pretty cool, I've never thought of logging my errors.

That is a really neat script. I will probaby implement it on my new site.

I had a script on our old server that scanned the error logs every hour and emailed the account owner / tech a list of the php errors that occured in that hour. I will see if I can find it...

Here is a mysql implementation of your script :


First create the table in the database by executing this query :

Code:

CREATE TABLE `error_log` (
  `date` datetime NOT NULL default '0000-00-00 00:00:00',
  `err_type` varchar(30) NOT NULL default '',
  `err_no` int(4) NOT NULL default '0',
  `err_str` text NOT NULL,
  `file` text NOT NULL,
  `line` int(8) NOT NULL default '0',
  KEY `date` (`date`,`err_no`),
  KEY ` err_type ` (`err_type`)
) TYPE=MyISAM;

Here is the php code :

Code:

<?php
function handler($errno, $errstr, $errfile, $errline)
 {
   global $config;
   $errortype = array (
          E_ERROR          => "Error",
          E_WARNING        => "Warning",
          E_PARSE          => "Parsing Error",
          E_NOTICE          => "Notice",
          E_CORE_ERROR      => "Core Error",
          E_CORE_WARNING    => "Core Warning",
          E_COMPILE_ERROR  => "Compile Error",
          E_COMPILE_WARNING => "Compile Warning",
          E_USER_ERROR      => "User Error",
          E_USER_WARNING    => "User Warning",
          E_USER_NOTICE    => "User Notice",
          E_STRICT          => "Runtime Notice"
    );
   
   if ( $errno != 2 && $errno != 8 )//This line is to avoid simple errors
   {
    $db_link = mysql_pconnect("host","user","pass");//Change this line and the next to your settings
    $db_name = "name_of_my_database";

    $errstr = str_replace("'", "\\'", $errstr);
    $errfile = str_replace("'", "\\'", $errfile);
    mysql_db_query($db_name,"INSERT LOW_PRIORITY INTO error_log VALUES(NOW(), '". $errortype[$errno] ."', '$errno', '$errstr', '$errfile', '$errline')", $db_link);
   }
 }
 set_error_handler("handler");
?>

That's a very nice implementation wolf.

I use something simmilar to this in my sites.

The only thing you should check is the mysql_pconnec command, because I think that not every hosting account allow persistant connections, so if you have problem with that you can replace it with mysql_connect(.....

There is another way to log the errors.

If you have access to the virtual host configuration file, you can add there this line :

Code:

php_value error_log "/path/to/my/logs/php.site.err"

This way the php will log all the errors to this file

OK I have found the script. Feel free to improve it!

Code:

NW... Sorry, I took so long to find it...

Wow, great script. I'll have to give that a try.

some webhosts like website source provide you with WebAlizer, which tracks everything included all errors.
